The Hex's Weakness
As the Praetor's body exploded, a powerful energy shockwave erupted all around it. I instinctively lifted my arms to defend myself, as did the girls, but I soon realized it didn't affect us at all. It passed straight through our bodies and rippled across the air, striking the other Hex.
Immediately, the Hex Troopers spasmed a bit, as if they'd been hit by some sort of electromagnetic ray that caused their insides to go haywire, and the single eye-like displays they had on their heads flickered a bit before fading out. The Troopers fell to the ground, immobilized and disabled, and making them completely vulnerable.
The girls didn't let go of this opportunity, naturally, and moved in to finish them off with a good few attacks on the core hiding within their exposed backs, guarded only by a metal gate. Several smaller explosions ensued, none of them affecting any of us, and soon, all the Hex on this floor had been cleared.
